The Nucleus of Noctiluca Scintillans
The unicellular organism, Noctiluca, has been examined with the electron microscope. The nucleus is small compared to the very large size of the cell, but the nuclear border has an organization which indicates an active nucleocytoplasmic exchange. Whereas annuli are missing over most parts of the nuclear membrane proper, there are "annulated vesicles" in a layer inside the nuclear membrane. The...
متن کاملGreen Noctiluca scintillans: a dinoflagellate with its own greenhouse
The effect of irradiance on photosynthesis of the green form of the dinoflagellate Noctiluca scintillans was studied. Photosynthesis, measured in cells collected from the field and without the addition of prey, increased with irradiance to ca. 200 ng C cell–1 d–1 at an irradiance of ~250 to 300 μmol photons m–2 s–1. N. scintillans cells were observed to prey and grow actively on a number of dif...
متن کاملTemporal abundance patterns of the red tide dinoflagellate Noctiluca scintillans along the southeast coast of Australia
Noctiluca scintillans was seasonally abundant during the austral spring and summer with typical values of 16 cells l–1, but depleted in autumn and winter, with values of <1 cell l–1. Peaks in abundance of up to 79 cells l–1 were observed, at the same time or subsequent to diatom blooms which were caused by episodic uplifting events during the spring and summer. The diatom blooms were dominated ...
متن کاملGrazing of heterotrophic dinoflagellate Noctiluca scintillans (Mcartney) Kofoid on Gymnodinium catenatum Graham.
A dinoflagellate bloom ("red tide" event) dominated by the toxic Gymnodinium catenatum Graham (Gymnodiniales, Dinophyceae; 99.7%) and the noxious Noctiluca scintillans (Mcartney) Kofoid (Noctilucaceae, Dinophyceae; 0.3%) was observed in Bahia de Mazatlán Bay, México, on 24-26 January 2000. Photographic and microscopic analysis of samples during such an event, allowed us to collect evidence of a...
متن کاملHigh turnover rates of copepod fecal pellets due to Noctiluca scintillans grazing
Copepod fecal pellet production and vertical flux, as well as vertical distributions of copepods, fecal pellets and the heterotrophic dinoflagellate Noctiluca scintillans were monitored in an upwelling plume off the coast of Brazil during 5 d in austral spring. Less than half (20 to 45%) of the pellets produced in the overlying water column reached sediment traps positioned at 30 to 60 m depth,...
